I have a 1996 Cherokee classic and I am starting to build it up for off-roading. although most of its in good shape, im afraid the rear axle will not be able to handle on trails. Its a Chrysler 8.25", c-clip, non-ABS, 27-spline axleshafts, with 3.73:1 gear ratios. I am looking to upgarde it and possibly swap it for better. any advice for what to look for would be helpful.
